Potato
As strange as it may sound, potatoes have an astringent effect that might help lessen irritation in the eyes! You can use it by simply putting slices of potato over your eyes for 10 to 15 minutes.
Artificial Tears
Simple eye drops can calm irritated eyes and aid in clearing out whatever may be causing the irritation. Pour two drops of fake tears into your eyes twice a day to help lubricate and hydrate them. However, you should only use eye drops twice a day at most, as over use might lead to dependency.
